` Gas AND LIQUID CONTACT DEVICE To all 'whom it, may con cer-n Be it known that EDWIN CLEARY, deceased, late a citizen of the United States of America, residing in London, England, has invented new and useful Improvements in Gas and Liquid Contact Devices, 'of which the following is a specification.

This invention relates to apparatus for effecting heat interchange between water or other liquids and gases, of the kind Wherein the liquid to be heated flows down a convoluted or zigzag path in contact with V- and on said baflies,

an ascending current of gas in -a tubular vessel or shell which is provided in its interior with central upwardly-concave baffles that are mounted on a supporting rod or standard and which alternatewith upwardly concave annular bailles that extend to the interior wall of the tubular shell. According to my invention, the parts of the concave baffles next the standard and shell are perforated so ascto allowalilm of liquid to flow down the surfaces of said standard and shell. The perforationsare small and serve also to prevent waterj being retained when the apparatus is not in use.

,By this means the gas in addition to pass- 'ing successively through annular screens of.

liquid falling from the free edgesof the bailles and overI the surfaces of liquid in passes over the films of liquid covering the Surfaces of the inner wall of the shell and of the standard sup` porting the central baiiles. A very extended liquid surface is thus oilered to the gases and the "rate of heat interchange is conse quently very rapid.

In the accompanying drawing, I have shown in vertical central section a cylindrical gas and liquid contact device constructed according to my invention A is the outer casing or shell, which is open at the bottom to admit a current of gas, and is closed at the top by means of a hood B provided with holesC,I C to permit the discharge of the gas. Coaxallv with the casing there .is mounted a stan Vard D, the upper lend of whichserves forv the admission of the water or other liquid, a flanged plug E being lower end to hold the ba hereinafter described, and another plug'v F frictionally or otherwise secured .in p ace Iiearthe top to confine the liquid to this end.

On the upper part of the` standard D there is secured a dome shaped defiector G, below which the series 'of holes H, the liquid issues in jets which strike the deflector Gand are deflected thereby'on to an annular dished baiiie J, which has its convex side upwards and'has a central-annular lip K over vwhich the liquid trickles in a the next baillelv L. This baille with the concave peripheral lip M over is a circular dished slde upwards and a pipe is provided with a Through these holes,

which the liquid trickles in a circular screen on to an annular dished baiiie N having its concave 'side upwards and a central circular lip O from which the liquid trickles on to a circular baille P similar to the baille L, and from P on to a baiiie Q. similar to N. From Q the hot liquid passes into a circular trough R, whence 1s flows without splashing through conduits S, S into an annular trough T having a discharge pipe- V con- A trolled by a suitable cock or valve. The lowermost parts of the baflles J, M, P are provided with an annular series ofholes W, W through which liquid trickles to form a screen or of the casing between the baffles J, N and down the surface of the standard D between the baiies L, P and between the baffie P and the trough R. These holes moreover allow the liquid resting on the baiiies J, L, AP to drain offfwhen the water supply ceases. The bafiies J, N, and Q are maintained at the required distances apart by tubular spacinipieces Y, Y Vformed integrally with es N, Q the entire stack of baffles being supported upon a tubular spacing piece Z, spacing pieces 1 1` act' in` con'unction with the flanged plug Eliiliid a nut i@ on'the upper part Vof the standard D retain the circular baffles L, P -and reservoir R in position, the stack of central baiies being supported by the lowermost spacing piece. Said trough is held in its central position by ra? prising an upright -shell' having a trough arranged peripherally inwardly at its lower end aEording a central opening for the pasfilm, 'down the peripheral wall- 'said opening,

range peripherally inwardly sage of gas through said shell, a reservoirl withinsaldshell secured in spaced relation to the wall thereof and positioned to confront a conduit leading from/said reservoir to said trough, cooperating stacks of central and peripheral batlies within said shell, arranged in interleaved relation, said bales being each formed with a spacing piece upon which rests the super-adjacent baille of its stack, means carried by said reservoir and shell for supporting said stacks of bafies, means for supplying water to said baies and a discharge pipe for said trough. y
